Productivity in the services sector: conventional and current explanations

One of the most conventional statements in economics, with regard to the services sector, suggests that, as a whole, this sector has a lower productivity level and growth rates than the other productive sectors. From this approach, we can derive the relative lower productivity in some advanced economies (such as the European countries versus the USA and some particular emergent economies) as an explanation of the growth of the tertiary sector. This paper will look in greater depth at issues related to services productivity, from conceptual aspects regarding the definition and meaning of productivity to methodological and measurement of services productivity. This work is essentially a necessary revision of the literature on economic growth, productivity and the services sector, reviewing not only the conventional literature but also those new waves of thinking.
